The F-22 community experienced five physiological events with hypoxia-like symptoms in the month of April. Prior to that, there had been nine incidents between June 2008 and February of this year, including one in which a pilot apparently lost his life.
So the USAF is getting around to looking at potential problems with the Raptor’s OBOGS:
The Air Combat Command on May 3 temporarily halted flights of the F-22 “until further notice,” according to an e-mailed statement from the command, based at Langley Air Force Base, Virginia. The Air Force has taken delivery of 160 of the stealth F-22 jets.
“The stand-down is a prudent measure following recent reports of potential oxygen system malfunctions” and gives Air Force officials time to investigate the system, the command said. The F-22 Raptor is the U.S. military’s most advanced fighter.
Fourteen incidents and a fatality in the last three years means it’s none too soon to figure this out.
LMCO’s F-35 program is hastening to distance themselves from Honeywell’s solution for their aircraft.
